Six-pion amplitude

Research output: Contribution to journal › Article › peer-review

Abstract

Within the framework of the massive nonlinear sigma model extended to the next-to-leading order in the chiral counting [for corresponding to the two(-quark)-flavor Chiral Perturbation Theory], we calculate the relativistic six-pion scattering amplitude at low energy up to and including terms . Results for the pion mass, decay constant, and four-pion amplitude in the case of (meson) flavors at are also presented.
